President Joe Biden appointed Phillips to the Federal Energy Regulatory Commission in September 2021 and he was confirmed unanimously by the Senate on November 16,[8] taking office on December 3, 2021. Phillips sees himself as a consensus-builder.[9]
After the expiration of Commissioner Richard Glick's term as chairman, Biden named Phillips acting chairman of the commission.[1] He is the first Black person to be serve as chair.[10] In July 2023, the Congressional Black Caucus wrote to President Biden to make Phillips the permanent chairman,[11][12] but the White House stated he was still the acting chairman, pending confirmation of a new chair, though observers state there is no difference.[13] On February 9, 2024, Biden officially designated Phillips as chair.[3]
Since Phillips became chair, the commission has approved multiple natural gas projects and pipelines,[14] resulting in criticism from environmental advocates.[15]
One of Phillips's priorities at the agency is to accelerate power plant interconnection and transmission planning.[16] In July 2023, it approved a rule directing how grid operators study proposed projects, which Phillips called "historic."[17] Phillips has also emphasized grid reliability during his term:[18] in May 2024, FERC approved a rule regarding interstate electricity transmission and cost-sharing of large projects.[19]
